Rectal - Cranial Inversion Syndrome. A way to say someones head is implanted firmly in thier ass and make it sound like the disease it usually is.

Man the boss must have a bad case of RCIS when he thought this up.

Hey did you catch a case of RCIS? Thats your girlfriends cousin you were trying to bang.

Rcis 

'Royale Concorde International School' is the full form of Rcis. The stupidest school to ever exist. They are sexist as fuck and bloody stalkers who stalk their students and appoint bloody no life people to find out info and snitch on these students

I don’t want to be in a school like Rcis
